Better to spend it on your own than trusting it to anyone especially here which is full of scammers. Also there's no assurance that they will give profit. Cryptocurrency market is very volatile as you can see. These so called portfolio managers or even cryptocurrency analysts can't predict it. So a piece of advice, don't trust any person with your money.
If you cannot handle your money and funds yourself, why would anyone else handle them with honesty.
Its better to develop enough skill in yourself to handle your money yourself.
Just hold some cryptocurrencies and sell them for higher price. That's called trading. It's better to play it yourself.
This is not trading and trading is not so simple. I have seen many people holding crypto and crying because their coins are dumping and their worth has become less. Even holding crypto especially the altcoins can be risky sometimes.
